Xen devel - Jan 2008 - KeGetCurrentProcessorNumber returning 256 under windows x64

Under windows 2003 x64, a call to KeGetCurrentProcessorNumber is
returning 256 in the ISR for my GPL PV drivers... Xen''s MAX_VIRT_CPUS
is
defined as 32 under this architecture, so when I go to look up the per
cpu data for that interrupt, we crash and burn.

I''m going to mask it with 31 for now (I''m just testing under
UP), but
this doesn''t sound like an ideal solution...

I''m running Xen 3.1.1 on an AMD dual core cpu.

Thanks

James
